Biplot pattern interaction analysis and statistical test for crossover and noncrossover genotype-by-environment interaction in peach
Angelini, Julia; Faviere, Gabriela Soledad; Bortolotto, Eugenia Belén; Arroyo, Luis Enrique; Valentini, Gabriel Hugo; Cervigni, Gerardo Domingo Lucio (Elsevier, 2019)The presence of genotype-by-environment interactions (GE) remains a major issue for crop improvement. The aims of this work were: i) to compare the efficiency of parametric and non-parametric methods to test the presence ... -
Comparison of methods for estimation of chilling and heat requirements of nectarine and peach genotypes for flowering
Maulión, Evangelina; Valentini, Gabriel Hugo; Kovalevski, Leandro; Prunello, Marcos; Monti, Laura Lucía; Daorden, Maria Elena; Quaglino, Marta; Cervigni, Gerardo Domingo Lucio (Elsevier, 2014-10-02)Chilling and heat requirements for breaking dormancy and flowering were studied in 63 nectarine and 118 peach genotypes (Prunus persica (L.) Batsch) for seven years. We compared two methods for estimation of requirements ... -
Identification of peach accessions stability and adaptability in non-balanced trials through years
Maulion, Evangelina; Arroyo, Luis Enrique; Daorden, Maria Elena; Valentini, Gabriel Hugo; Cervigni, Gerardo Domingo Lucio (2016)Identification of genotypes with acceptable yield and yield stability in different environments is an important issue in plant breeding. Genotype-by-environment interaction (GEI) can alter genotypes performances making the ... -
Parameter estimation and selection efficiency under Bayesian and frequentist approaches in peach trials
Angelini, Julia; Bortolotto, Eugenia Belén; Faviere, Gabriela Soledad; Pairoba, Claudio Fabián; Valentini, Gabriel Hugo; Cervigni, Gerardo Domingo Lucio (Springer Nature, 2022-07)Identification of stable and high-yielding genotypes is a real challenge in peach breeding, since genotype-by-environment interaction (GE) masks the performance of the materials. The aim of this work was to evaluate the ... -
Performance profiling of Prunus persica (L.) Batsch collection and comprehensive association among fruit quality, agronomic and phenological traits
Maulion, Evangelina; Arroyo, Luis Enrique; Daorden, Maria Elena; Valentini, Gabriel Hugo; Cervigni, Gerardo Domingo Lucio (2016-01-01)Nowadays, although there are several studies based on peach phenotypic diversity and adaptability,there is no current research regarding associations among characters using multivariate statistical meth-ods which provide ... -
Study of statistic stability to select high-yielding and stable peach genotypes
Maulión, Evangelina; Valentini, Gabriel Hugo; Ornella, Leonardo Alfredo; Pairoba, Claudio Fabián; Daorden, Maria Elena; Cervigni, Gerardo Domingo Lucio (Elsevier, 2014-08-15)In peach breeding, suitable identification methods for performance stability studies as well as the associations between stability parameters are poorly understood. Therefore, the aims of this work were to compare parametric ...
